Description of problem: Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. I have two systems on two separate hard disks. Each is a fedora system. 2. Disk 1 is fc7 32 bit 3. Disk 2 is fc7 64 bit I had trouble with yum that would not use a freshrpms repro. I changed Selinux to permissive, and did the scan on system 1 Actual results: System 1 was unaffected, but since the / file system from system 2 was mounted via fstab could not be logged into, it appears that X windows on the system 2 got corrupted, and X windows complained about an error preventing a logon, even as root. Expected results: Did not expect 2nd system to block logons. Additional info: The first system (32bit fc7) /dev/main/root / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/main/tmp /tmp ext3 defaults 1 2 /dev/main/data /data ext3 defaults 1 2 /dev/main/swap swap swap defaults 0 0 /dev/main/home /home ext3 defaults 1 2 ####### this file is for install on the maxtor hda drive (200gig) ######### ####### below is the fstab for the fc7 64 bit system ######### /dev/MainSda/root /sdaroot ext3 defaults 1 1 LABEL=/boot1 /sdaboot ext3 defaults 1 2 /dev/MainSda/data /sdadata ext3 defaults 1 2 /dev/MainSda/home /sdahome ext3 defaults 1 2 /dev/MainSda/tmp /sdatmp ext3 defaults 1 2 What I eventually did, is reinstall the second system.
This sounds like you relabeled one system while the other was mounted, thus destroying the second file systems labeling. A relabel will cause all file systems currently mounted to be labeled according the OS that is doing the labeling. You could have rebooted the second system in permissive mode and caused it to do a relabel. In order to relabel you need to either unmount the alternate systems shares before relabeling or mount the secondary shares file system with a context mount option.
